Wind fan, an air outlet corresponding with air-out fan position is made on the top at cabinet back door, in the bottom at cabinet back door
An air inlet corresponding with air inlet fan position is made, the air inlet is with air outlet by the logical of a plurality of setting side by side up and down
Wind gap form, and between air inlet fan and air inlet, filtering web is provided between air-out fan and air outlet.
Moreover, described ventilation gaps integrated punching on cabinet back door is made.
Moreover, installation temperature controller in described cabinet, the temperature controller connect air intake by contactor or solid-state relay
Fan and air-out fan, air inlet fan connect power supply with air-out fan, power supply connection temperature controller.
Moreover, described temperature controller passes through background computer in RS485 interface docking stations.
The advantages of the utility model and good effect are：
1st, the utility model respectively installs a fan up and down at transformer station's master control room protection screen cabinet back door, and back door top and the bottom are equal
It is equipped with a plurality of gap and screen pack cotton is installed, be air inlet below, be air outlet above, is opened automatically using temperature controller control fan
Open and close, to reach the effect for forcing wind to circulate.
2nd, the utility model is opened and closed automatically using temperature controller switch board internal fan, is accelerated radiating, can effectively be dropped
It is low to be overheated and the fault rate of initiation by protection device, it is ensured that protective relaying device safe and stable operation, to greatly improve making for device
With the life-span, maintenance cost is reduced.
3rd, the utility model is also arrived at a station the information transmission such as in-cabinet temperature value and temperature controller failure using the RS485 communication technologys
Interior background computer, and then main website is arrived, the application of RS485 mechanicss of communication can ensure that scheduling operator on duty grasps in-cabinet temperature letter in real time
Whether breath and temperature controller are in normal operating conditions, once temperature controller breaks down, will receive fault message from the background, so that
Failure obtains timely processing.
4th, the utility model is provided with filter cotton between air inlet fan and air inlet, between air-out fan and air outlet
Net, it can play a part of filtering dust, keep air cleaner.
5th, the utility model is that a kind of reasonable in design, scientific structure, transformer station's wall that easy to use, practicality is good are set
Standby temperature control type heat abstractor, the present apparatus respectively install a fan up and down in bay device rear cabinet door, and wind is controlled using temperature controller
The opening and closing of fan, so as to accelerate air flow in cabinet, heat is discharged in time, ensure that the normal fortune of power transformation station equipment
OK, potential safety hazard is eliminated, while information is passed to by backstage by RS485 communications, to monitor in real time, further increases electric power
